Soil is the basic environmental element of the ecosystem and the material basis for human survival and development, so it is important to strengthen the prevention and control of soil pollution and analysis of physical and chemical properties. In addition, soil as the basis of agricultural development, agriculture also has a pivotal role, what kind of soil is suitable for what kind of crops, to absorb the crop growth process and what elements are still missing, etc. can be detected through soil analysis to obtain results. In addition to testing the plasticity index of soil samples, Lifeasible can also use various methods to test the LL (liquid limit), SL (shrinkage limit), flow index, toughness index, fluidity index/hydroplasticity ratio, and other indicators of soil samples.
